Biocomputing with Martyn Amos

The Jan 30th This Week in Science Podcast covers various topics including:

Today’s interview with Biocomputing expert, Martyn Amos, was a fascinating journey into the future of technology. What we consider computers today won’t be the computers of tomorrow, and computers will likely be integrated into all aspects of life using the miniaturization potential of DNA. While we are still far away from the realization of many aspects of biocomputing, it has come a long way from its humble beginnings.

NSF’s K-12 Math and Science Partnerships

NSF’s Math and Science Partnerships Demonstrate Continued Increases in Student Proficiency:

NSF’s MSP program supports partnerships among higher education, local K-12 school systems, and supporting stakeholders, such as businesses or informal science-education organizations. At a minimum, each partnership must contain one institution of higher education and one K-12 school system. The program’s portfolio includes 52 partnerships and more than 30 other projects engaged in the development of tools, research and capacity building for evaluation to support the work of the partnerships.
…
An analysis of 123 schools participating in the National Science Foundation (NSF) Math and Science Partnership (MSP) program shows improvements in student proficiency in mathematics and science at the elementary, middle- and high-school levels over a 3-year period.

Cancer Cure - Not so Fast

Follow up on Cheap, Safe Cancer Drug?: In which my words will be misinterpreted as “proof” that I am a “pharma shill”:

This drug has only been tested in cell culture and rats. Yes, the results were promising there, but that does not–I repeat, does not– mean the results will translate to humans. In fact, most likely, they will not. Those of us who’ve been in the cancer field a while know that all too common are drugs that kill tumors in the Petrie dish and in mice or rats but fail to be nearly as impressive when tested in humans.

Perhaps the blog post I quote above just resonates with me (see: confirmation bias). To me,it supports my contention in my “Cheap, Safe Cancer Drug?” post, though much more effectively and with supporting evidence. But this is my blog so I get to quote whoever I want, and it isn’t surprising I find those that share my thoughts to be the most compelling Anyway the post I quote is definitely worth reading.

‘Hobbit’ human is a new species

‘Hobbit’ human ‘is a new species’:

Archaeologists had found sophisticated tools and evidence of a fire near the remains of the 1m-tall adult female. “People refused to believe that someone with that small of a brain could make the tools,” said Professor Falk. She said the Hobbit brain was nothing like that of a microcephalic and was advanced in a way that is different from living humans.

A previous study of LB1’s endocast revealed that large parts of the frontal lobe and other anatomical features were consistent with higher cognitive processes. “LB1 has a highly evolved brain,” said Professor Falk. “It didn’t get bigger, it got rewired and reorganised, and that’s very interesting.”

Nanoscale Universe Experience

Riding Snowflakes is a production exploring the nanoscale universe projected on digital-domes (planetariums) funded by NSF and created by RPI. A teacher’s guide provides experiments and activity-based lessons for to introduce, reinforce and expand upon key concepts presented in the show.

Generating the molecular worlds described in the screenplay entailed a wide range of challenges in statistical mechanics, molecular modeling, and simulation. To create a truly immersive portal into the nanoscale universe required simulations of a massive scale and complexity - an entirely unusual request for the chemical and biological engineers and scientists involved in the project. The creation of a believable and cinematic molecular landscape to visualize the plot twists and dramatic tension of the story posed a host of new creative challenges for the collaborating scientists. Their involvement in this work has brought about insights that will hopefully spark a breakthrough in the very real worlds of energy, environment, and health.

Scientists and Engineers Without Borders

Building on the Doctors without Borders organization are two organizations: Science without Borders and Engineers without Borders.

Science Without Borders:

Scientists may not provide emergency relief in times of disaster, but the discipline has a major role to play in meeting the chronic needs of our planet: health, agriculture, environment, energy, and many more. By creating Scientists Without Borders, the Academy aims to facilitate synergies among institutions already committed to the UN Millennium Development Goals as well as to unleash the energy of thousands of scientists in academia and industry. With the benefit of the best and most current information, they can apply their efforts to training health workers and researchers in developing countries or devote part of their research efforts to address underserved global challenges.

Engineers Without Borders (USA):

The activities of EWB-USA range from the construction of sustainable systems that developing communities can own and operate without external assistance, to empowering such communities by enhancing local, technical, managerial, and entrepreneurial skills. These projects are initiated by, and completed with, contributions from the host community working with our project teams.

Educating the Engineer of 2020: NAE Report

Educating the Engineer of 2020:

The BS degree should be considered as a pre-engineering or “engineer in training” degree.

I am not convinced of this idea. It seems to me a BS degrees in engineering should be a full degree not some “pre” degree like pre-law. Obviously no engineering degree is an invitation to stop learning; life long learning is a requirement whether the engineering degree is earned in 4, 6, 8… years. Improving the life long learning methods is where effort should be focused in my opinion not in making the original degree take longer to earn.

The engineering education establishment should participate in efforts to improve public understanding of engineering and the technology literacy of the public and efforts to improve math, science and engineering education at the K-12 level.
NSF should collect or assist collection of data on program approach and student outcomes for engineering departments/schools so prospective freshman can

These seem like good ideas to me.

Other than trying to get people to buy the content that they provide for free I can’t understand why they present the material so poorly online. Once again basic web usability principles are lacking on their site.

Robots for Space Exploration

Robot Subs in Space James Vlahos:

But now, after spending nearly three decades on the margins of the space industry, Stone is closer than he’s ever been to proving that caves are the best earthly training ground for exploring space. Backed by a $5-million grant from NASA, he is developing a robot called DepthX that may turn out to be the most advanced autonomous underwater vehicle (AUV) ever. Like its inventor, DepthX is a caver, capable of navigating constrained, obstacle-filled environments. Its theoretical mission, though, is bold even by Stone’s standards: a hunt for extraterrestrial life on the Jovian moon of Europa.

A ‘Chunnel’ for Spain and Morocco

From the bustling waterfront of this African port city, Europe appears tantalizingly close: The coast of Spain shows on the horizon just nine miles away. Despite decades of dreaming, no one has been able to bridge the physical divide that opened between the two continents more than 5 million years ago, forming the geological bottleneck to the Mediterranean Sea.

In recent months, however, the governments of Morocco and Spain have taken significant steps to move forward with plans to bore a railroad under the muddy bottom of the Strait of Gibraltar. If built, the project would rank among the world’s most ambitious and complex civil engineering feats, alongside the Panama Canal and the Channel Tunnel between Britain and France.

Anger at Anti-Open Access PR

Post angry at the anti open access moves by science journals are exploding. Which is a good thing; hopefully the momentum will keep up and some real changes will take place.

Those with money to lose will fight against freedom of information by Bora Zivkovic, is pretty representative:

While the world is moving towards an Open Science model of exchange of scientific information, there are, as expected, forces that are trying to oppose it. Whenever there is a movement to change any kind of system, those most likely to lose will make a last-ditch and nasty effort to temporarily derail the progress.

More: My advice to the American Chemical Society - Big Content’s ‘pitbull’ and the AAA - Science Journals Hire “PR Pit Bull” - Traditional science publishers hire PR firms to scuttle open access - The Open Access “Debate” - A quick bit on the future of Open Access Publishing, Anthropology, and Public Relations - More on the AAP PR campaign - Anti-Open Access Propaganda: An Institution Under Siege - Science publishers get stupid

Good. Go blogosphere, Go Open Access and Go Badgers, too.

Germany’s Science Chancellor

The Science Chancellor:

Angela Merkel, a physical chemist-turned-G8 leader, is putting science on the European and global agenda
…
Merkel touted a new €6 billion fund for innovative “beacon projects,” plus an increase in R&D funding to 3 percent of Germany’s $2.5 billion GDP through 2010. She’s also made an impact on the German science community. “They’re all impressed that a scientist, a real scientist who really did scientific work and didn’t just get a degree and move on, finally made it to the top of the political ladder,”

Eat food. Not too much. Mostly plants.

Excellent articles on eating healthy but also provides a nice insight in the practice scientific inquiry: Unhappy Meals by Michael Pollan:

Eat food. Not too much. Mostly plants. That, more or less, is the short answer to the supposedly incredibly complicated and confusing question of what we humans should eat in order to be maximally healthy.

That is the advice on how to eat more healthfully by Michael Pollan the author of The Omnivore’s Dilemma

If nutritional scientists know this, why do they do it anyway? Because a nutrient bias is built into the way science is done: scientists need individual variables they can isolate. Yet even the simplest food is a hopelessly complex thing to study, a virtual wilderness of chemical compounds, many of which exist in complex and dynamic relation to one another, and all of which together are in the process of changing from one state to another. So if you’re a nutritional scientist, you do the only thing you can do, given the tools at your disposal: break the thing down into its component parts and study those one by one, even if that means ignoring complex interactions and contexts, as well as the fact that the whole may be more than, or just different from, the sum of its parts. This is what we mean by reductionist science.

Interactions are critical in many experiments. That is why multi-factor experimentation is so important (One-Factor-at-a-Time Versus Designed Experiments) though even using these techniques the complexity of interactions provides an incredibly challenging environment.

More Microchip Breakthroughs

Intel, IBM separately reveal transistor breakthrough

In dueling announcements, Intel Corp. and International Business Machines Corp. separately say they have solved a puzzle perplexing the semiconductor industry about how to reduce energy loss in microchip transistors as the technology shrinks to the atomic scale.

Each company said it has devised a way to replace problematic but vital materials in the transistors of computer chips that have begun leaking too much electric current as the circuitry on those chips gets smaller. Technology experts said it’s the most dramatic overhaul of transistor technology for computer chips since the 1960s
…
The problem is that the silicon dioxide used for more than 40 years as an insulator inside transistors has been shaved so thin that an increasing amount of current is seeping through, wasting electricity and generating unnecessary heat. Intel and IBM said they have discovered a way to replace that material with various metals in parts called the gate, which turns the transistor on and off, and the gate dielectric, an insulating layer, which helps improve transistor performance and retain more energy.

The Future of the Scholarly Journal

Publishing Group Hires ‘Pit Bull of PR’:

Those groups, along with many members of Congress, want to make the published results of federally financed medical research freely available to the public whose taxes funded the work — results that today are typically available only to journal subscribers or to people willing to pay expensive per-page fees.

The publishing association, which includes among its members some of the world’s biggest and most profitable scientific journals, has argued that free Internet access to the publicly funded portion of their contents would undermine their subscription bases. Lacking that income, they claim, they would not be able to do the invisible, unsung but important, work of screening out bad science and publishing and archiving the very best.

As I have said before, this information should be publicly available. The funding mechanism for peer review needs to change. If the Journals want to stay in business they need to find a way to add value that doesn’t keep public funded information from the public.

Waterloo’s wizards of game theory

16,777,236 - That’s the number of outcomes that are possible when eight competitors each consider three strategic options.

The first step was to get executives from IBM into a room to start mapping out the game. For the math in game theory to work effectively, all players capable of influencing the game must be identified and their potential options listed and ranked. At this stage, clients are asked to draw on a wide range of personnel, since, in the case of IBM, its marketing people would likely have a different perspective on Microsoft than would its engineers. Once the group is assembled, they are asked to determine what objectives another company is likely to pursue. “Frequently they will say to us, ‘Well, we don’t know about those competitors.’ And our answer is, ‘Yes, you do,’ ” Mitchell says.
…
California Institute of Technology professor R. Preston McAfee, a leading game theorist who helped the U.S. government design auctions for broadband spectrum, says doubters ought to remember that game theory is a tool, not an answer. “Game theory is sometimes criticized because it doesn’t actually completely solve the problem,” McAfee says. “On the other hand, the exercise of applying game theory very often clears up things that you can dispense with—issues that aren’t salient to the decision process. Sometimes just thinking it through identifies strategies that you hadn’t thought available.”

Entrepreneurial Engineers

Business Leader Says Today’s Engineers Have to Be Entrepreneurial:

“Every engineer and scientist entering the job market today needs to be entrepreneurial, whether or not they plan to start their own business,” says Donna Novitsky, partner at venture capital firm Mohr Davidow Ventures and adjunct professor in the School of Engineering. “It’s no longer an optional job qualification. It’s a ticket to entry in leading companies, even for undergrads.”

Strong words. A great resource mentioned in the article Stanford Technology Ventures Program Educators Corner, includes a large number of podcasts and short (2 - 10 minute video webcasts):

Stanford Technology Ventures Program (STVP) Educators Corner is a free online archive of entrepreneurship resources for teaching and learning. The mission of the project is to support and encourage faculty around the world who teach entrepreneurship to future scientists and engineers, as well as those in management and other disciplines.
